posterior mesonotum sloping through a feeble convexity 
posteriorly. Metanotal groove obsolete; propodeum ex- 
tremely feebly convex in dorsal outline, beginning at the 
foot of the posterior mesonotal slope and itself sloping 
posteriorly, but much more gently so. Propodeal teeth 
long (0.10 mm.) and stout, acute, obliquely elevated; in- 
fradental lamellae very narrow, concave, widening below 
into low, convex metapleural lobes. 
Petiole with very slender peduncle, longer than the sub- 
globose free portion of the node, which is about as broad 
as long and has a feeble longitudinal carinula running over 
each dorsolateral surface. Posterior neck of petiole partly 
covered by the narrow spongiform collar, which widens 
a bit on each side to form a broadly rounded posterolateral 
spongiform lobe. Midventral spongy strip well developed. 
Postpetiole moderate in size, slightly broader than long 
and distinctly broader than the petiole, its disc convex and 
surrounded by spongiform margins ; well developed spongi- 
form masses posterolaterally and ventrally. Gaster with 
ventral surface much more strongly convex than dorsum; 
anterior spongiform margin narrow dorsally, its edge 
gently raised and convex in the middle. Basal gastric 
costulae rather irregular and indefinite, extending about 
the length of the basal tergite; gastric surface other- 
wise smooth and shining. 
Head, including scapes and dorsal surfaces of mandibles, 
dorsum of alitrunk, legs and petiole densely and finely 
granulose-punctulate, opaque. Much of sides of alitrunk 
and dorsal surface of postpetiole with punctulation partial- 
ly effaced, weakly shining to subopaque. 
Cephalic dorsum, mandibles, scapes and promesonotum 
with a regular and dense pilosity consisting of small, 
numerous, subappressed to subreclinate, spatulate to in- 
verted-spoon-shaped hairs, on the dorsum of the head ap- 
pearing like small oval scales. Anterior scape border with 
a regular, prominent row of outstanding narrowly spoon- 
shaped hairs, prevailingly slightly oblique apicad. Special- 
ized erect pilosity of head and alitrunk lacking, except for 
a single weakly differentiated suberect spatulate hair on 
the extremity of each occipital lobe. Propodeum, anterior 
of petiolar node and legs with a sparse growth of small.
